q
Set
the caching of display methods correctly depending on their usage.
Infrequently used display methods should not be
cached.
q
Set
OnlyFetchActive=Yes on datasources if no fields from the table are being used
in X++
This optimizes the amount of data that is fetched from
the database and moved from the database, to the AOS and finally to the client.
q
Set
AutoSearch=No on infrequently used datasources and only execute the query when
the data is displayed
q
Enable
or disable controls in a single RPC call to the server.
This means that you get all relevant data needed, and then enable or
disable controls on the form based on the data. Do not get a specific piece of
data, disable a control, and then get another piece of data (database call),
and disable a control, and repeat the process until you have worked through the
display elements.
q
Wrap
calls that cause a layout change or window redraws in element.lock() and
element.unLock() to minimize extraneous drawing that result in flicker.
The element.lock() and element.unlock() methods are new in Dynamics AX
2012. When the form is 'locked', the form will not be redrawn (changes in the
layout will not be addressed). Once a form is 'unlocked' any layout changes
will be made. This has been implemented as a way of minimizing the times a form
has to update the layout.
q
Minimize
the work that you do in a datasource's active() method.
Like accessing additional database, complex calculations in
datasource's active() method.
q
Make
first FactBox on your form cheap to display.
The first FactBox is expanded initially by default,the
data retrieved for the fact box is not a complex query, and that it will
execute quickly.
q
Correctly
set the LinkType property of datasources to minimize the number of queries sent
to the server.
